hi ive searched but cannot find what i need. i have the stri boost gauge and i was wondering where you guys wire your constant 12v source wire and your ignition on wire. i get mine to turn on and do the sweep but afterwards it just sits at 30 psi without the car on and then i turn the car on and it does the sweep again and stays at 30 psi. the gauge doesnt move or respond to me pressing the gas. just wondering if wiring those two wires would do this or if the map sensor is bad. thanks in advance.
